Harry (name changed), a 40-year-old man, visited a doctor with complaints of leg pain while walking. On further enquiry, it was revealed that he had been consuming alcohol regularly for more than a decade. Clinical evaluation led to a diagnosis of peripheral vascular disease (PVD). ALSO READ: Why being tough matters for a healthy life Peripheral vascular (or arterial) disease is a slowly progressive condition in which the arteries—blood vessels that carry blood from the heart to different parts of the body—become narrowed, thereby reducing blood supply. The legs are most commonly affected, leading to pain during walking. ALSO READ: What excess of nutritional supplements can do Regular alcohol consumption significantly increases the risk of developing PVD. Alcohol enhances oxidative stress and inflammation in the inner lining of blood vessels. This promotes the buildup of fatty plaques (atherosclerosis) within the vessel walls, narrowing the lumen and restricting blood flow to the limbs and other body parts. ALSO READ: The benefits of physical work Alcohol intake is also a risk factor for high blood pressure, which further contributes to the narrowing of blood vessels. Additionally, it can cause dyslipidemia—elevated levels of harmful lipids in the blood—which accelerates atherosclerosis. Chronic alcohol use also increases the likelihood of clot formation within arteries, leading to blockages that further reduce blood flow. ALSO READ: Mitigating health challenges in era of remote work, learning All these factors impair circulation to the limbs, resulting in pain during movement or physical activity. This occurs because the increased oxygen demand during exertion cannot be met due to limited blood supply. Alcohol-induced vasodilation can cause pooling of blood in the legs, placing pressure on veins and potentially leading to chronic venous insufficiency. It also increases the risk of deep vein thrombosis. Furthermore, chronic alcohol use directly damages peripheral nerves, which can worsen limb pain associated with PVD. Nutritional deficiencies caused by prolonged alcohol use further impair tissue health and the body’s ability to repair vascular damage. The severity of symptoms depends on several factors, including age, gender, duration and quantity of alcohol consumption, alcohol content of the beverages consumed, tobacco use, and the individual’s overall health. Stopping or significantly reducing alcohol intake can help prevent further damage, although recovery depends on the extent of existing disease. A healthy lifestyle plays a crucial role in preventing PVD or minimizing its severity. This includes a balanced, nutritious diet, regular exercise, and adequate rest. Avoiding or limiting alcohol is beneficial in both preventing the onset and slowing the progression of the disease. Exercise should be tailored to an individual’s physical capacity. Walking or jogging up to the point of pain, then resting and gradually increasing the distance over time, is an effective way to condition the leg muscles and improve endurance. PVD is diagnosed based on clinical symptoms, physical examination, and imaging techniques such as ultrasound and angiography. Once established, the condition is generally not reversible, but treatment can help slow its progression and alleviate symptoms. Management typically includes medications such as blood thinners, antiplatelet agents, lipid-lowering drugs, and vasodilators, used in appropriate combinations. Nutritional deficiencies are addressed through dietary improvement and supplementation where necessary. In cases of multiple blockages or severe symptoms, interventional procedures such as angioplasty, stent placement, or thrombolytic therapy may be required. In advanced stages, amputation may unfortunately be the only option. It is equally important to manage coexisting conditions such as hypertension and diabetes, which can further impair blood flow and worsen arterial disease. Awareness of peripheral vascular disease and the role of alcohol in its development and progression is essential. Early intervention, including lifestyle modification and appropriate medical treatment, can help prevent disease progression and reduce the risk of serious complications.
